The way that Network Virtualization is implemented in Hyper-V and subsequently in Microsoft Azure IaaS, enables explicitly the Routing between Virtual Subnets. This is the reason why the traffic between Virtual Subnets, that are part of the same Virtual Network, is unrestricted unless we have applied Network Security Groups.

When we create a VM on Azure, at the same time we create a Cloud Service. Later we can create more VMs on the same cloud service. Each cloud service has a unique Public IP. For as long the Cloud Service has at least one VS running this Public IP remains the same. If all VMs of a Cloud Service are off then the Public IP is released and next time the VM is powered on it will take a new Public IP.
Using PowerShell we can reserve a Public IP for as long as the Cloud Service exists, with or witho
Από το SQL Server 2012 και πάνω έχει αλλάξει η συμπεριφορά του Identity property. Σε αυτό το web cast δείχνω την νέα και τι αυτή φέρνει σαν επιπτώσεις στην καθημερινή μας εργασία

Κάθε φορά που στο μυαλό σου έρχεται η σκέψη να κάνεις upgrade ένα υπάρχον SQL Server instance ή κάποιες databases σε επόμενη έκδοση τα αισθήματα σου είναι ανάμικτα. Από την μια λες πρέπει να γίνει καθώς θα πάω σε κάτι νέο με περισσότερα χαρακτηριστικά και δυνατότητες και έτσι θα είμαι σε θέση να παρέχω καλύτερες υπηρεσίες στους χρήστες μου. Από την άλλη αναρωτιέσαι αν αυτό θα σου δημιουργήσει προβλήματα καθώς μπορεί κάποια πράγματα μπορεί να μην δουλέψουν γιατί μπορεί να μην υπάρχει συμβατότητα

Using Transport rules, you can look for specific conditions in messages that pass through your organization and take action on them. Transport rules let you apply messaging policies to email messages, secure messages, protect messaging systems, and prevent information leakage.
Many organizations today are required by law, regulatory requirements, or company policies to apply messaging policies that limit the interaction between recipients and senders, both inside and outside the organization. I

Today, I manage to complete the bellow script, in order some basic Office 365 User Creation and License assignment to be automate with one click.
This script automate execute steps for Office 365 Administrator Tasks.
By choosing only a number, you can manage your Office 365 Tasks.
What do you need to know before you begin?
Make sure you have already installed Windows Azure AD PowerShell
You must check and be sure your server or your computer has access to the internet

The DirSync by default runs every three hours. And you will realized that there is no GUI way to change that. To change the sync interval we need to change a configuration file. 1. Go to the below directory on your DirSync Server: C:\Program Files\WindowsAzureActiveDirectorySync (there are two similar directories, one with spaces between the words and one without. We want the one without spaces) Here we will find the main executable of the DirSync Scheduler, the “Microsoft.Online.DirSync.Schedul
This is a fast way to manage Calendar permissions of a mailbox. Same commands are for both Exchange on-premises and Exchange Online (Office 365). For Exchange Online first connect Powershell to Office365, as described to previous posts.
# To check current permissions
Get-MailboxFolderPermission -Identity "[email protected]":\calendar
# To add calendar permissions, permission can be Editor,Reviewer,Author etc
Add-MailboxFolderPermission -Identity "[email protected]":\calendar -User "mana
You can easily provide Full Access Permissions using the GUI, just Edit the mailbox you want, go to Mailbox Delegation and provide Full Access. Both Exchange 2013 and Online is the same. But if you have to provide Full Access massively then you need PowerShell.
The command for a single user is:
Add-MailboxPermission -Identity "employee" -User "manager" -AccessRights FullAccess
with that command user “manager” will be granded with Full Access permissions to user “employee”
Now lets see
1. Check if the password is set to never expire for one user:
Get-MSOLUser -UserPrincipalName username | Select PasswordNeverExpires
2. Check if the password is set to never expire for all users:
Get-MSOLUser | Select UserPrincipalName, PasswordNeverExpires
3. Check if the password is set to never expire for a list of users:
create a txt file listing the required users, line by line with title “username”, and save it as c:\pwdexpire.txt, like this:
username testuser1 test
Αυτό το post είναι οι σημειώσεις μου από διάφορα migrations Exchange 2007 & 2010 σε Office 365 Hybrid Deployment. Για Exchange 2013 είναι σχεδόν το ίδιο, αλλά αρκετά πιο εύκολο! Όπως είπα είναι οι σημειώσει μου μαζί με διάφορες προσθέσεις από διάφορα blogs, κάτι σαν Checklist και όχι Tytorial ή Guide.

Εδώ και αρκετό καιρό έχω γίνει αποδέκτης αρκετών ερωτήσεων σχετικά με τα σεμινάρια της Microsoft για τον SQL Server και συγκεκριμένα για τις εκδόσεις του 2012 & 2014. Οι ερωτήσεις αφορούν θέματα περιεχομένου και πιστοποίησης.

Every time I present a session about Microsoft Azure IaaS, the most common question is about Virtual Machines’ capability of getting more than one Virtual Network Interface (vNIC). At TechEd Europe 2014, Microsoft announced support for multiple Network Interfaces (vNICs) in Azure VMs, as well as other additions to Azure Virtual Networks like Network Security Groups.
Moreover, the capability of adding more than one vNIC to a Virtual Machine will enable Virtual Appliances scenarios like Firewalls
